Safety Heads commonly come in three series compatible in orifice sizes and maximum pressure ratings with Autoclave low, medium and high-pressure valves, fittings and tubing.

Safety Heads

High Pressure Safety Heads up to 60,000 PSI

The male inlet design can be inserted directly into the tubing connections of valves and various fittings such as tees and crosses, or located in pressure vessels.

Outlet connections are 3/8" pipe (NPT). This outlet may be connected to a suitable discharge line to vent pressure to a safe location in the event of bursting of the rupture disc. Torque required for sealing rupture discs will range from 40 to 90 foot pounds, depending upon pressure and media being used.

Material of body and hold down nut is high tensile 316 stainless steel. Standard tubing glands and collars are provided unless otherwise specified.


Common Applications

  • Gas
  • Liquid
  • Fluid handling for the chemical/petrochemical, research, and oil and gas industries


Typical Advantages

Reduced Inventory Costs

One head fits most standard international flanges eliminating the need to stock unnecessary and costly inventory.

Simple, Fail-Safe Installation

The asymmetric locating pins and standard welded J-Bolt ensure correct orientation by eliminating possible human error.

Easy Cleaning and Inspection

Maintenance can be done without replacing the disk due to the pretorqued cap screws, which maintain the clamping load on the disk.
